Когда я пытаюсь запустить работника сельдерея с ./manage.py celeryd --loglevel=DEBUG, возникает исключение ImportError.
Но если я добавлю строку, которая вызывает исключение в интерпретаторе python:
>>> from select import error as SelectError, poll
Работает без проблем. Я не понимаю, почему импорт сельдерея проваливается.
Вот трассировка:
/usr/local/lib/python2.7/dist-packages/djcelery/loaders.py:103: UserWarning: Using settings.DEBUG leads to a memory leak, never use this setting in production environments!
warnings.warn("Using settings.DEBUG leads to a memory leak, never "
